 vhost/virtio-user loopback with multi-queues test plan
 ======================================================
 
-This test plan test vhost/virtio-user loopback multi-queues with split virtqueue and packed virtqueue different rx/tx paths, includes split virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test, and packed virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable path. And virtio-user support 8 queues in maximum, check performance could be linear growth when enable 8 queues and 8 cores, notice cores should in same socket.
+This test plan test loopback multi-queues with split virtqueue mergeable, non-mergeable, vectorized_rx,
+inorder mergeable, inorder non-mergeable path, and packed virtqueue mergeable, non-mergeable，inorder mergeable,
+inorder non-mergeable, vectorized path. And virtio-user support 8 queues in maximum, check performance could be
+linear growth when enable 8 queues and 8 cores, notice cores should in same socket.
+Note: Packed virtqueue vectorized path need below three initial requirements:
+    1. AVX512 is allowed in config file and supported by compiler
+    2. Host cpu support AVX512F
+    3. ring size is power of two
